The AirTAC GFR60020MLC2G AirTAC G3/4 Filter Regulator, 40 um is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/4" ports, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR60020MLC2G is a size-600 GFR filter regulator: water and particulate filtration plus pressure regulation combined in one body. This configuration is built around G3/4 (3/4 inch) ports with G (BSPP) thread, a 40 um standard filter element, and a manual drain you operate by hand to empty the bowl. It is the low-pressure regulator type, and it ships with a round external gauge reading in psi so the set pressure is visible at the wall of the unit. Because this is the 600 size, the bowl is aluminium alloy, and the maximum inlet pressure is 1.0 MPa (145 psi) with an operating temperature range of -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600, with port options from 1/8 to 1 inch, a choice of 40 um or 5 um (W) filtration, manual, automatic or differential-pressure drains, gauge and scale options, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing figures for your application before ordering.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

On a CNC machining cell, the GFR60020MLC2G cleans water and swarf-carrying compressed air and holds a reduced, low-pressure setting for clamping fixtures that must not crush aluminium workpieces, with the psi gauge giving the operator a visible setpoint.
Feeding an air knife or blow-off manifold above a packaging conveyor, this unit filters line air to 40 um and regulates it down to the gentle pressure the product needs, while the manual drain lets the shift operator clear accumulated condensate at start-up.
In a spray or coating booth, atomizing air must be clean, dry and held at a low, stable pressure. This filter regulator conditions the supply, protects the gun from water and particulate, and lets the technician read and repeat the set pressure in psi.
Start with the port and size step: this unit is the 600 frame at G3/4, the largest in the GFR line, so step down to a 200/300/400 GFR if your line runs smaller ports and lower air demand. Choose the drain to match access: manual (this unit) suits attended installations where an operator can bleed the bowl; automatic or differential-pressure drains suit unattended duty. Pick 40 um for general air preparation or the 5 um (W) element where downstream valves and instruments need finer filtration. Gauge scale is selectable (MPa, psi or bar) and the thread can be ordered as PT (standard), G or NPT; a mounting bracket is included.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated number, and the exact regulated range of the low-pressure type is not listed as a figure. Ask us to confirm flow and regulation data against your application before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR family as curves rather than a single rated figure, so we do not quote a number on the page. Tell us your line pressure, port size and air demand, and we will confirm the flow and sizing data from the datasheet for this exact model before you order.
The M code means the bowl is emptied by hand: an operator opens the drain to release collected water. It suits installations that are checked daily. If the unit sits in an inaccessible or unattended position, order the automatic (A) or differential-pressure (blank) drain variant instead - the rest of the specification stays the same.
